FIELD

The present technology relates to aryl or heteroaryl triazolone derivatives or pharmaceutically acceptable salts thereof having inhibitory activity on vascular adhesion protein (VAP-1), a process for the preparation thereof, a pharmaceutical composition comprising the same, and uses thereof.

BACKGROUND

Vascular adhesion protein-1 (VAP-1) is a semicarbazide-sensitive amine oxidase (SSAO), which is abundantly present in human plasma. VAP-1 is an ectoenzyme comprising a short cytoplasmic tail, a single transmembrane domain, and an extracellular domain with large and high glycosylation containing the center of activity. In addition, VAP-1 exists not only as a membrane-bound form in the endothelium, but also as a soluble form in serums (soluble VAP-1, sVAP-1). This form was shown to be a product cleaved from the membrane-bound VAP-1, and appears to have similar properties as the tissue-bound form. It has been also reported that VAP-1 is normally stored in intracellular granules within endothelial cells, but when an inflammatory response is evoked in response to inflammatory stimuli, it is translocated onto the cell membrane, and its expression is unregulated, and therefore, it is expressed more strongly in inflamed tissues than in normal tissues.

Substrates for VAP-1 include endogenous methylamine and aminoacetone as well as some xenobiotic amines such as tyramine and benzylamine.

VAP-1 has two physiological functions: the first is amine oxidase activity stated earlier in this section, and the second is cell adhesion activity. Due to these two activities, VAP-1 has been shown to play a key role in the leakage of inflammatory cells as it acts as an adhesion protein for leukocytes in inflamed sites [Trends Immunol. (2001) 22: 211]. VAP-1-deficient transgenic mice are healthy, develop normally, and fertile, and phenotypically normal, but exhibit a marked decrease in the inflammatory responses evoked in response to various inflammatory stimuli [Immunity. (2005) 22: 105].

In addition, inhibitory activity of VAP-1 in multiple animal models of human diseases (e.g., carrageenan-induced paw inflammation, oxazolone-induced colitis, lipopolysaccharide-induced lung inflammation, collagen-induced arthritis, endotoxin-induced uveitis) by the use of antibodies or small molecules has been shown to prevent leukocyte from rolling, adhering, and leaking, and reduce levels of inflammatory cytokines and chemokines, thereby reducing the severity of the disease [Eur J Immunol. (2005) 35: 3119; J Pharmacol Exp Ther. (2005) 315: 553; Annu Rep Med Chem. (2007) 42: 229; FASEB J. (2008) 22: 1094]. Inflammation is the first reaction of the immune system to infection or stimulus and in such a process, the movement of leukocytes into the tissue through circulation is an important step. The leukocytes are first bound to adhesion proteins and then adhered to the endothelium before they start to pass through blood vessel walls. VAP-1 is highly expressed in endothelial venules (HEV) such as high endothelial venules in lymphoid organs, as well as hepatic sinusoidal endothelial cells, (HSEC), smooth muscle cells, and adipocytes. The VAP-1 expression on the cell surface of endothelial cells is strictly regulated and is increased during inflammation. VAP-1 activates NF-κB when it is present in the substrate, and the NF-κB is activated within the HSEC while E-selectin and chemokine IL-8 that are other adhesion molecules are upregulated ex vivo. This suggests that VAP-1 may be a key factor for the regulation of the inflammatory response, and it seems therefore likely that VAP-1 inhibitors may be effective anti-inflammatory drugs in a wide range of human diseases.

Nonalcoholic fatty liver disease (NAFLD), histologically, encompasses simple steatosis, nonalcoholic hepatosteatosis (NASH), and liver cirrhosis. Among these, unlike simple steatosis (non-alcoholic fatty liver, NAFL), NASH potentially progresses to liver cirrhosis and hepatoma (hepatocellular carcinoma). In NASH, insulin resistance is known to play an important role in the progression of disease, along with oxidative stress, inflammatory cascade, and fibrosis. In patients with NAFLD, sVAP-1 levels were found to be elevated, and in VAP-1 knockout (K/O) mice, carbon tetrachloride-induced liver fibrosis was reduced compared with that in wild type animals. In addition, improvement of liver fibrosis by VAP-1 inhibition following administration of VAP-1 antibody was identified by histological changes [J Clin Invest (2015) 125: 501]. Thus, VAP-1 was found to be associated with NASH in clinical studies and animal models of diseases. Inhibitory activity of VAP-1 in the carbon tetrachloride-induced animal model appears to be due to a reduction in infiltration of leukocytes such as T cells, B cells, NKT cells, and NK cells observed in liver fibrosis, and VAP-1 inhibitors have the potential for treating fibrotic diseases.

Thus, a substance that inhibits VAP-1 may be applied to prevention and treatment of various inflammatory diseases and fibrotic diseases.

DETAILED DESCRIPTION

It is noted that, as used herein and in the appended claims, the singular forms “a”, “an”, and “the” include plural referents unless the context clearly dictates otherwise. It is further noted that the claims may be drafted to exclude any optional element. As such, this statement is intended to serve as antecedent basis for use of such exclusive terminology as “solely”, “only” and the like in connection with the recitation of claim elements, or use of a “negative” limitation.

As used herein, the term “comprising” or “comprises” is intended to mean that the compositions and methods include the recited elements, but not excluding others. A composition or method “consisting essentially” of the elements as defined herein would not exclude other materials or steps that do not materially affect the basic and novel characteristic(s) of the claimed technology. “Consisting of” shall mean excluding more than trace elements of other ingredients and substantial method steps. Embodiments defined by each of these transition terms are within the scope of this technology. When an embodiment is defined by one of these terms (e.g., “comprising”) it should be understood that this disclosure also includes alternative embodiments, such as “consisting essentially of” and “consisting of” for said embodiment.

“Substantially” or “essentially” means nearly totally or completely, for instance, 95%, 96%, 97%, 98%, 99% or greater of some given quantity.

As used herein, the term “about” will be understood by persons of ordinary skill in the art and will vary to some extent depending upon the context in which it is used. If there are uses of the term which are not clear to persons of ordinary skill in the art given the context in which it is used, “about” will mean up to plus or minus 10% of the particular term.

Certain ranges are presented herein with numerical values being preceded by the term “about”. The term “about” is used herein to provide literal support for the exact number that it precedes, as well as a number that is near to or approximately the number that the term precedes. In determining whether a number is near to or approximately a specifically recited number, the near or approximating unrecited number may be a number which, in the context in which it is presented, provides the substantial equivalent of the specifically recited number.

Where a range of values is provided, it is understood that each intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise, between the upper and lower limit of that range and any other stated or intervening value in that stated range, is encompassed within the present technology. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges and are also encompassed within the present technology, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the present technology.

In general, “substituted” refers to an organic group (e.g., an alkyl group) in which one or more bonds to a hydrogen atom contained therein are replaced by a bond to non-hydrogen or non-carbon atoms. Substituted groups also include groups in which one or more bonds to a carbon(s) or hydrogen(s) atom are replaced by one or more bonds, including double or triple bonds, to a heteroatom. The present disclosure is understood to include embodiments where, for instance a “substituted alkyl” optionally contains one or more alkene and/or alkyne. A substituted group will be substituted with one or more substituents, unless otherwise specified. In some embodiments, a substituted group is substituted with 1, 2, 3, 4, 5, or 6 substituents. Examples of substituent groups include: halogens (i.e., F, Cl, Br, and I); hydroxyls; alkoxy, alkenoxy, alkynoxy, aryloxy, aralkyloxy, heterocyclyloxy, and heterocyclylalkoxy groups; aryl groups; heteroaryl groups; cycloalkyl groups; heterocyclyl groups; carbonyls (oxo); carboxyls; esters; carbamates; urethanes; ureas; oximes; hydroxylamines; alkoxyamines; aralkoxyamines; thiols; sulfides; sulfoxides; sulfones; sulfonyls; sulfonamides; amines; N-oxides; hydrazines; hydrazides; hydrazones; azides; amides; ureas; amidines; guanidines; enamines; imides; isocyanates; isothiocyanates; cyanates; thiocyanates; imines; nitro groups; nitriles (i.e., CN); and the like.

Substituted ring groups such as substituted cyclic, substituted cycloalkyl, substituted aryl, substituted heterocyclic and substituted heteroaryl groups also include rings and fused ring systems in which a bond to a hydrogen atom is replaced with a bond to a carbon atom. Therefore, substituted cyclic, substituted cycloalkyl, substituted aryl, substituted heterocyclic and substituted heteroaryl groups may also be substituted with substituted or unsubstituted alkyl, alkenyl, and alkynyl groups as defined below.

As used herein, the term “cyclic ring” refers to an aromatic or non-aromatic ring, optionally containing one or more heteroatoms. Exemplary heteroatoms include, but are not limited to, N, O, S, or B. In some embodiments, the cyclic ring optionally contains 1 to 5 heteroatom ring members chosen from O, N, or S. In some embodiments, the cyclic ring optionally contains 1 to 4 heteroatom ring members chosen from O, N, or S. In some embodiments, the cyclic ring optionally contains 1 to 3 heteroatom ring members chosen from O, N, or S. Cyclic rings include aryl, cycloalkyl, and heterocyclic groups.

As used herein, an “aryl group” refers to a cyclic aromatic hydrocarbon that does not contain heteroatoms. Aryl groups include monocyclic, bicyclic and polycyclic ring systems. Thus, aryl groups include, but are not limited to, phenyl, azulenyl, heptalenyl, biphenylenyl, indacenyl, fluorenyl, phenanthrenyl, triphenylenyl, pyrenyl, naphthacenyl, chrysenyl, biphenyl, anthracenyl, indenyl, indanyl, pentalenyl, and naphthyl groups. In some embodiments, aryl groups contain 6-14 carbons, and in others from 6 to 12 or even 6-10 carbon atoms in the ring portions of the groups. Although the phrase “aryl groups” includes groups containing fused rings, such as fused aromatic-aliphatic ring systems (e.g., indanyl, tetrahydronaphthyl, and the like), it does not include aryl groups that have other groups, such as alkyl or halo groups, bonded to one of the ring members. Rather, groups such as tolyl are referred to as substituted aryl groups. Representative substituted aryl groups may be mono-substituted or substituted more than once. For example, monosubstituted aryl groups include, but are not limited to, 2-, 3-, 4-, 5-, or 6-substituted phenyl or naphthyl groups, which may be substituted with substituents such as those listed above.

As used herein, the term “cycloalkyl group” refers to a cyclic alkyl group such as, but not limited to, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, and cyclooctyl groups. In some embodiments, the cycloalkyl group has 3 to 8 carbon ring members, whereas in other embodiments the number of ring carbon atoms range from 3 to 5, 3 to 6, or 3 to 7. Cycloalkyl groups further include mono-, bicyclic and polycyclic ring systems, such as, for example bridged cycloalkyl groups as described below, and fused rings, such as, but not limited to, decalinyl, and the like. In some embodiments, polycyclic cycloalkyl groups have three rings. Substituted cycloalkyl groups may be substituted one or more times with non-hydrogen and non-carbon groups as defined above. However, substituted cycloalkyl groups also include rings that are substituted with straight or branched chain alkyl groups as defined above. Representative substituted cycloalkyl groups may be mono-substituted or substituted more than once, such as, but not limited to, 2,2-, 2,3-, 2,4- 2,5- or 2,6-di-substituted cyclohexyl groups, which may be substituted with substituents such as those listed above. In some embodiments, a cycloalkyl group has one or more alkene bonds, but is not aromatic.

As used herein, the term “heterocyclic group” includes aromatic (also referred to as heteroaryl) and non-aromatic ring compounds containing 3 or more ring members, of which one or more is a heteroatom such as, but not limited to, N, O, S or B. In some embodiments, heterocyclic groups include 3 to 20 ring members, whereas other such groups have 3 to 6, 3 to 10, 3 to 12, or 3 to 15 ring members. Heterocyclic groups encompass unsaturated, partially saturated and saturated ring systems, such as, for example, imidazolyl, imidazolinyl and imidazolidinyl groups. The phrase “heterocyclic group” includes fused ring species including those comprising fused aromatic and non-aromatic groups, such as, for example, benzotriazolyl, 2,3-dihydrobenzo[1,4]dioxinyl, and benzo[1,3]dioxolyl. The phrase also includes bridged polycyclic ring systems containing a heteroatom such as, but not limited to, quinuclidyl. However, the phrase does not include heterocyclic groups that have other groups, such as alkyl, oxo or halo groups, bonded to one of the ring members. Rather, these are referred to as “substituted heterocyclic groups”.

Experimental Example 1: Activity Evaluation with Respect to Amine Oxidases

The compounds according to the present technology were evaluated in terms of activity on recombinant human VAP-1 (R&D systems) by measuring the level of hydrogen peroxide in horseradish peroxidase (HRP)-coupled reaction using Amplex Red Hydrogen Peroxide Assay Kit (Molecular Probes, Invitrogen, USA). The experiment was carried out at room temperature using benzylamine as a substrate. In the HRP-coupled reaction, hydrogen peroxide oxidation of 10-acetyl-3,7-dihydroxyphenoxazine (Amplex Red reagent) produces resorufin, which is a highly fluorescent compound. Briefly, the test compound was dissolved in dimethyl sulfoxide (DMSO) at a concentration of 20 mM. The dose-response assessment was made by 1:3 serial dilution in DMSO, thereby creating an 8 point curve. The concentration of the upper part was controlled according to the efficacy of the compounds, followed by dilution with a reaction buffer solution to obtain a final DMSO concentration less than 1%. To each well of a 96 black well plate, human VAP-1 purified in 50 mM sodium phosphate buffer solution (pH7.4) was added. The test compounds dissolved in DMSO were incubated with the human VAP-1 enzymes at 37° C. for 30 minutes. After 30-minute incubation, each well is added with a reaction mixture containing 200 uM Amplex Red reagent prepared from 50 mM sodium phosphate buffer solution (pH 7.4), 1 mM benzylamine, and 1 U/mL HRP. Fluorescence intensity was measured at several time points during 1-2 hours using a microplate reader (Flexstation3, Molecular Devices) under the wavelength condition exciting at 544 nm and reading the emission at 590 nm. The inhibitory effect of the compounds was measured as a decrease (%) in the signal rate as compared to the control group without any inhibitor (only diluted DMSO). Data was fixed to a logistic model with four variables and IC₅₀ value was calculated using GraphPad Prism program.

In addition, the compounds according to the present technology were evaluated in terms of activity on a recombinant human MAO-A (monoamine oxidase-A, Sigma-Aldrich) and a recombinant human MAO-B (monoamine oxidase-B, Sigma-Aldrich) by using as substrates, 0.5 mM tyramine and 1 mM benzylamine, respectively, with a method similar to the activity evaluation method for recombinant human VAP-1. The compounds according to the present technology were also evaluated in terms of activity on a recombinant human DAO (diamine oxidase, R&D systems) by using as a substrate 1 mM putrescine with a method similar to the activity evaluation method for recombinant human VAP-1.
